context_section_description: The railway line is graded by Rete Ferroviaria Italiana as a secondary, low-traffic line.
  It is a single-track railway for its entire extension, and it is not electrified, so it is run with diesel multiple units: currently FCU ALn 776 (on the Terni-L'Aquila route) and Pesa Atribo "Swing" (on the L'Aquila-Sulmona route).
  The line features some of the most steep climbs of the standard gauge, non-rack Italian rail system: from the Antrodoco-Borgo Velino station until the Sassa-Tornimparte station, where the line crosses the Apennine Mountains that divide Lazio from Abruzzo, it has a steepness of 35‰; the highest point of the line is the Sella di Corno railway station, at 989.28 metres on the sea level. From the Terni station until the Marmore station the line climbs the drop of altitude near the Marmore falls with a steepness of 30‰.
  Maximum allowed speeds vary for each stretch of the line; the highest is 110 kilometres per hour (68 mph), which is reached in the straight and flat stretch between Contigliano and Marmore, while the lowest is 55 kilometres per hour (34 mph), which is reached in the winding trait between Antrodoco and Rocca di Fondi, at the start of the Apennine pass.
  Signalling on the line is operated by Centralized traffic control while safety is assured by Sistema Supporto Condotta and by automatic axle-counting block system; installation of these systems took place from 1989 to 1993.
